Whenever code expands and becomes complex, we can segregate and categorize the Jasmine specs corresponding to a specific feature or component. In this recipe, you will learn how to organize Jasmine specs into groups and subgroups. Jasmine provides the describe global function to define group-related specs. The string parameter of the describe function is used to name the collection of specs, which represents a specific feature or component. This helps in finding specs and corresponding JavaScript code in a large suite. The name of the collection of specs is further concatenated with the name(s) of subgroup(s) to make a spec's full name. Moreover, if we name them well, we can read specs as a full sentence.

You will learn this recipe with the help of the second recipe in this chapter, Implementing the Jasmine test corresponding to the specs.
